DETAILED DESCRIPTION

In one or more embodiments of the invention, wearable monitors and/or sensors are provided which may communicate wirelessly with a mobile device such as a cellular telephone, personal digital assistant (PDA) or other portable computing device. The monitor may be mounted on a user such that the monitor measures biometric information of the user. This information may be communicated to a portable computing device. Based on this information, the portable computing device may control and dynamically change a computer game to encourage exercise. The user may also directly control the game by controlling their biometrics.

In one example, a wrist, ankle, neck, thigh, back, head, hair, ear, eye, mouth, nose, finger, toe, or any other suitable body part/area band, strap, belt, bracelet, cover, shirt, pant, sock, glove, clip, or any other practicable securing mechanism may include one or more monitors or sensors adapted to sense biometric information from a user and to transmit this information to a cellular telephone, personal digital assistant or other portable device. Based on this information, the computing device may control aspects of a computer game. For instance, the user may control the actions of an avatar based on their biometric data.

If the user's biometric information is not within a predetermined range, the mobile computing device may modify the game play to encourage the user to keep their biometric data within the predetermined range. Exemplary biometric information that may be monitored includes, but is not limited to, heart rate, pulse rate, temperature, respiration, acceleration, skin resistivity, sweat, electrical impulses, positions of body parts (e.g., relative position of hands and feet), etc. Based on this information, a computing device can determine the type of exercise the user is performing, the length of time the user is performing the exercise, the level of fatigue of the user, etc.

In some embodiments, a retaining mechanism (e.g., a band or bracelet) may be provided at any suitable monitoring location, such as arms, legs or head of a user, to monitor movements and/or other biometrics of the user. In some embodiments, a retaining mechanism may be provided for each arm and/or each ankle of a user to monitor arm and/or leg position during exercise, golf, tennis, running, pushups, sit-ups, callisthenic exercise, weightlifting workouts (e.g., kettlebell workouts, etc.) etc. Such a system may be used, for example, to determine if the user has correct form during exercise, stride length during running, body position during a golf or tennis swing, “hang time” during a basketball dunk, and the like. In some embodiments, bands or bracelets may be provided for the torso, abdominals and/or the head of a user.

In some embodiments, a camera or other imaging device may be used with or without a band or bracelet to determine the biometric data and/or movements of a user. In some embodiments the imaging device may be mounted on the user and/or be part of the mobile computing device. In some embodiments, exercise equipment, such as a kettlebell, may be equipped with a monitor that may be used with or without an imaging device, band or a bracelet to determine biometric data of the user.

In one or more embodiments, an accelerometer may be provided within a retaining mechanism (e.g., a band or bracelet). The accelerometer may be employed to measure acceleration during a golf, tennis, hockey or other swing. Such acceleration information may be wirelessly transmitted to a computing device such as a cellular telephone, personal digital assistant or other portable device, and used to determine club, racquet or stick speed, club, racquet or stick velocity, swing tempo, or the like. In some embodiments, such acceleration information may be adjusted to compensate for the affects of gravity. In some embodiments, the accelerometer may be employed to measure acceleration during exercise, and the computing device may provide feedback to the user if the acceleration is within a range that may cause injury, or if the acceleration is outside of a predetermined range.

Software and/or one or more computer program products on the mobile computing device, such as a cellular telephone or other portable device, may be employed to calculate or otherwise determine any relevant information. A user can download the software using the internet, Bluetooth™, or any other suitable wireless protocol. A wireless or wired protocol may also be used to download software to the mobile computing device. The mobile computing device may store any information or software on a tangible, computer readable medium.

FIG. 1 is a schematic diagram of an exemplary system 100 for sensing, collecting and/or monitoring biometric information from a user (not shown). The example system 100 includes a wearable band 102 having one or more monitors or sensors (not shown) adapted to monitor or otherwise sense, for example, heart rate, pulse rate, temperature, respiration, acceleration, skin resistivity, or any other biometric information. The wearable band 102 may (wirelessly) transmit the biometric information to one or more cellular telephones 104 a-b or other portable devices such as personal digital assistants, MP3 players, portable video game players, other portable computing devices, or the like. While two cellular telephones are shown in FIG. 1, it will be understood that any number of portable or mobile computing devices (e.g., 1, 2, 3, 4, 5, etc.), differing types of mobile computing devices, etc., may receive biometric information from the band 102.

Each cellular telephone 104 a-b, or any other mobile computing device receiving information from the band 102, may be programmed to process the biometric information received from the band 102 (e.g., for general health monitoring, determining swing information, monitoring sleep patterns, enhancing video game performance by affecting a video game character or characteristic based on the biometric information, etc.).

In some embodiments, the band 102 may be flexible, continuous, sealed, adjustable, and/or water resistant.

FIG. 2 is a schematic diagram of an alternative system 200 for sensing, collecting and/or monitoring biometric information from a user (not shown). In the embodiment of FIG. 2, four bands 102 a-d communicate information to a cellular telephone 104 (or other mobile computing device). For example, a user may employ a band 102 on each arm and each ankle, or multiple users may employ a band 102. Other numbers of bands and/or portable computing devices may be used.

FIG. 3 illustrates an exemplary method 300 provided in accordance with the present invention. In step 302, the video game begins. The video game may include one or more aspects that are controlled by the user. The user may control the one or more aspects of the game based at least in part upon their biometrics. In some embodiments, the user may control the actions of an avatar or character in the game using the user's real world biometrics. In other words, by manipulating the user's own real world biometrics (e.g., heart rate), the user may directly control one or more parts/functions of the game and/or the user's avatar in the game.

In step 304, the user may exercise. By exercising, the user may control/manipulate and change his/her biometrics, and in turn control the avatar. As discussed above, biometric data may include heart rate, pulse rate, temperature, respiration, acceleration, skin resistivity, sweat, electrical impulses, position(s) of body parts (e.g., hands and/or feet), etc.

In step 306, one or more biometrics of the user are monitored by one or more sensors coupled to the user (e.g., one or more bands 102 of FIG. 1), exercise equipment, and/or a suitable imaging device.

In step 308, the monitored biometric(s), referred to herein as monitored biometric parameter(s) (MBP(s)) or just biometric parameters, are communicated to a mobile or portable computing device, such as a cell phone or PDA (e.g., cell phone 104 a and/or 104 b in FIG. 1). Each MBP may be communicated to the mobile computing device using a wired protocol or wireless protocol such as Bluetooth™ or via the internet.

In step 310, the mobile computing device may determine information relating to the exercise the user is performing (e.g., the type of the exercise the user is performing, duration of exercise, frequency of the exercise, etc.) based on the received MBP. The user may move differently during different exercises. If the user is wearing monitors on all four appendages, the relative motions and/or distances between appendages may be determined. For instance, during a pushup the user's hands and feet may remain mostly stationary, while during jumping jacks the users hands and feet move away from each other, and then towards each other. Based upon the relative motion and/or position of the appendages of the user, the mobile computing device may determine whether the user is performing jumping jacks or pushups. Thus, information relating to exercise may be determined by analyzing the relative positions and/or movements of the user's body parts. Of course, the computing device may also determine any number of other parameters such as heart rate, pulse rate, temperature, respiration, acceleration, skin resistivity, sweat, electrical impulses, etc.

In step 312, the computing device may determine if an action should be taken in the video game based upon the user's MBP. For instance, by performing a certain exercise (e.g., pushup, sit-up, jogging, pull-up, etc.), the avatar in the video game may perform an action (e.g., move up, down, left, right, etc.). In some embodiments, the user may be required to perform a certain amount of exercise, such as 10 pushups, before an action is performed in the video game. In some embodiments, the user must maintain his/her heart rate within a predetermined range or above/below a predetermined threshold before an action is performed in the game. In some embodiments, an exercise must be performed for a predetermined amount of time before an action is performed in the video game. If the computing device determines no action should be taken, the method returns to step 306 to repeat steps 306-312 (e.g., until the computing device determines an action should be taken in the video game, until a victory or fail condition is met in the video game, etc.). Note that some game actions may involve direct control of the avatar's actions (e.g., speed of the avatar, whether the avatar is standing or sitting, etc.) and some game actions may involve alteration of aspects of the game itself (e.g., the size of an object, the slope of an incline).

In step 314, if the computing device determines in step 312 that an action should be taken, the avatar performs an action in the video game (e.g., move the avatar, extend the life of the avatar, give the avatar additional powers, make the avatar larger and/or stronger, or otherwise allow the avatar to perform better in the game) or the game itself is otherwise altered.

Steps 302-314 may then repeat (e.g., until the user stops video game play and/or exercise).

In some embodiments of the invention, a video game is provided that motivates a user to exercise harder, more vigorously, longer, within a target range (e.g., within a defined heart rate or pulse-ox range), to achieve a fitness goal, to exercise more, faster, slower, or the like. The game is adapted to provide gaming entertainment to the user during exercise so that the user may be distracted from the work of the exercise. As illustrated in FIG. 4A, in one exemplary video game 400, called “Boulder Push” or “BP”, an exerciser is provided with an avatar 402 that may or may not look like the exerciser. In some embodiments, the exerciser may customize the appearance of the avatar 402 (e.g., size, weight, clothing, gender, hair color, etc.). Further, exercise of the user may influence characteristics of the avatar (e.g., size, strength, stamina, etc.).

The video game 400 may start with the avatar 402 holding an object 404 (e.g., a boulder) on or near an incline 406 (e.g., a hill). One or more biometric parameters of the exerciser such as heart rate, pace, distance traveled, number of steps, etc., may be monitored (e.g., via a wrist band, chest strap, or the like, in communication with a game system such as a mobile computing device, cellphone, PDA, etc.). As the MBP of the exerciser changes, the avatar 402 may begin causing the object 404 to move up or down the incline 406. If the exerciser's MBP falls below a predetermined threshold, the movement of the object 404 up the incline 406, for example, may begin to slow down or reverse, for example. If the exerciser's MBP falls too low, the avatar 402 may lose control of the object 404 which may roll backward toward and/or crush the avatar 402. In some embodiments, if the exerciser's MBP falls above a predetermined threshold or outside a target range, the object 404 may slow down, stop rolling and/or begin to roll down the incline 406. In some embodiments, if the MBP falls above a predetermined threshold, the avatar 402 may reflect the fatigue of the exerciser by slowing down and/or by visually sweating or panting. In this manner, the exerciser is motivated to maintain his/her MBP within a desired range or to follow a defined pattern. A message (not shown) may flash on the video game screen and/or be audibly presented advising the exerciser to speed up, slow down or otherwise alter his/her exercise. The MBP also may be displayed along with an indication of the target range or predefined threshold required by the game.

In some embodiments, video game play or aspects of the game itself may dynamically change such that the slope/terrain of the incline 406 and/or the size/shape/type of the object 404 may change and may even be adjustable by the exerciser (e.g., by touching an input device such as a cellular phone running the video game, based on user heart rate or another biometric parameter, etc.). For instance, if the MBP is outside of a given range, the object 404 may increase in size or the incline 406 may become steeper. Sounds generated by the mobile computing device may be used to indicate the changes or other aspects of the game.

In some embodiments, the exerciser may design the characteristics of the incline 406 prior to or during exercise. In some embodiments, predefined incline 406 patterns may be selected that correspond to particular fitness or other goals. At the end or at some other milestone during an exercise routine, the avatar 402 may reach a summit of the incline 406, or roll the object 404 into one or more valleys. In some embodiments, the object 404 may roll down the other side of the incline 406 and crush a target such as trees, cars, a town, another player, or the like. In some embodiments, the object 404 may, for example, plug a crater of a volcano that is about to erupt (e.g., and failure to plug the crater within a predetermined time period may cause the demise of the avatar and/or other elements of the video game).

In some embodiments, the video game 400 may contain several challenges to motivate the exerciser to exercise. For instance, the characteristics of the incline 406 may change so that the exerciser has to control the avatar 402 to move the object 404 to the sides of the incline 406 (e.g., left or right) and/or let the object 404 move downhill to avoid obstacles, such as dead ends along a path or rocks that block the path of the avatar 402. Thus, the exerciser may control the avatar 402 to perform several different actions such as pushing the object 404 to the left, pushing the object 404 to the right, pushing the object 404 uphill, allowing the object 404 to move downhill, picking up the object 404, throwing the object 404, smashing the object 404 into smaller pieces, etc.

The exerciser may need to perform different physical exercises in the real world to control the avatar 402 to perform different actions in the game world. For instance, the exerciser may need to jog or run in the real world to cause the avatar 402 to push the object 404 up the incline 406 in the game, but perform pushups to push the object 404 to the left, perform sit-ups to move the object 404 to the right and perform jumping jacks to move the object 404 downhill. In some embodiments, the exerciser's MBP must stay within a desired range for a predetermined amount of time, such as 10 seconds, before an action, such as pushing the object 404, is performed.

The actions of the avatar may be controlled through any suitable MBP. In some embodiments, if the exerciser's heart rate is within a predetermined range, the avatar may perform a specific action. Several ranges may be selected so that different heart rates correspond to different actions the avatar may perform.

By having different exercises control different aspects of the video game 400, the exerciser may be encouraged to have a well balanced work out. For instance, the exerciser may exercise several muscle groups (e.g., pectorals, triceps, quadriceps, abdominals, biceps, etc.) and also use cardiovascular exercise to complete the video game.

In this manner a exerciser may have to complete one or more “circuits” to finish the video game or complete a level/portion of the video game. A circuit may be a combination of high-intensity aerobics and resistance training, for example. In some embodiments, a circuit is designed to be easy to follow and target fat loss, muscle building and/or heart fitness. An exercise circuit is one completion of all prescribed exercises. When one circuit is complete, the exerciser may stop exercising, begin the first exercise again for another circuit or start an entirely different exercise routine or circuit. In some embodiments, the time between exercises in circuit training may be short, often with rapid movement to the next exercise. An exemplary circuit may include:

-   -   1. Arms—pull-up or push-up     -   2. Abs—sit ups     -   3. Legs—step ups     -   4. Arms—shoulder press     -   5. Abs—sit-ups or plank exercises     -   6. Legs—burpees

A burpee is a full body exercise used in strength training and as aerobic exercise. It is performed in several steps and starts from a standing position: 1) the user drops into a squat position with their hands on the floor in front of them, 2) the user kicks their feet back, while simultaneously lowering themselves into a pushup 3) the user immediately returns their feet to the squat position, while simultaneously pushing up with their arms and 4) the user leaps up as high as possible from the squat position with their arms overhead. In some embodiments, more or fewer exercises may be used in a circuit. For instance, a user may be required to jog between different exercises.

As discussed above, the exerciser may be required to complete one or more circuits to finish the video game 400. Each exercise of the circuit may correspond to a different action of the avatar 402. For instance, sit-ups may correspond to pushing the object 404 uphill, while push-ups may correspond to pushing the object 404 to the left and so forth. The exerciser may be presented with several challenges or obstacles that require the avatar 402 to perform different actions, which in turn correspond to different exercises the exerciser must perform. Thus, the challenges or obstacles in the video game 400 may be selected such that the exerciser completes all of the exercises in a circuit, or several circuits, to finish the video game 400 or complete a level of the video game 400.

In some embodiments, the computing device used to execute the video game 400 may be portable and may be transported by the exerciser during exercise. Thus, the exerciser may not necessarily be tied to a specific location during video game play. For instance, the exerciser may be required to do pushups at a first location, and then jog a predetermined distance away from the first location and arrive at a second location. The exerciser may then be required to perform another exercise at the second location and then jog another predetermined distance away and arrive at a third location. The exerciser may then perform another exercise at the third location. This may repeat until the game is completed. Accordingly, the exerciser is not tied to a specific location during game play. For instance, a exerciser may play the video game 400 outside of his/her home at any number of locations (e.g., park, track, gym, etc.), and transport the computing device during exercise.

Multiplayer embodiments may be employed in which the avatars of players compete against one another or work together to move an object. For example, FIG. 4B illustrates a first avatar 402 a and a second avatar 402 b competitively rolling a single object 404 up and over a incline 406 at each other. In other embodiments, each avatar may roll a different object up the same (or a different) incline or toward another avatar or avatar's object (e.g., to block the other avatar's progress). Any number of players and/or avatars may be employed including multiple avatars for each user.

In some embodiments, different users can network their devices together via the internet. The users' computing devices may be connected to a server, or directly to each other. Any wired or wireless protocol may be used to connect the users' computing devices for multiplayer game play.

Any software discussed in this application may be implemented on a computing device or system, and saved onto a tangible, computer readable medium of the computing device or system.

In some embodiments, the object 404 may grow in size and/or weight as it rolls up the incline 406 (e.g., if the incline is snow covered). Alternatively, the object may erode or otherwise shrink in size and/or weight as it rolls up the incline 406.

While the present invention has been described primarily with regarding to video games operating on portable computing devices such as cellular telephones, PDAs, MP3 players, tablet computers, etc., it will be understood that other computing devices may be employed for similar exercise-controlled video game play such as desktop computers, non-portable video game players, etc.

Any methods or processes described herein may be implemented in software as a computer program product. Each computer program product may be carried by a medium readable by a computer (e.g., a carrier wave signal, a floppy disc, a hard drive, a random access memory, etc.).
